I am working for a major ISP company in Greece. A few months ago, we had some problems with the nms software we used to monitor all network devices, so i was assigned the -pretty difficult- task of finding a new and most reliable nms software. I started testing several of them about 4 months ago, from the cheaper to the most expensinve, including HP OpenView.

The two biggest problems i faced were the cost of each one and the cpu load they needed for monitoring several hunderds of network devices.

HM was not my first choise, i admit i didn't know about it till then. But once i started testing it, i realized that it really could do almost everything i needed, using very small cpu and ram loads, at a very good price and with a very good support team.

At this moment, the company i work for has purchased an Enterprise License and i have already configured about 2000 tests, without having any problems whatsoever
